Despite efforts to increase the diversity of cancer clinical trial participants, African Americans are still underrepresented. While perceptions of participation have been studied, the objective of this study was to compare perceptions and decisional conflict towards clinical trials among African American cancer patients who have and have not participated in clinical trials to identify key areas for intervention. Post hoc analysis also looked at whether they had been asked to participate and how that group differed from those who did. Forty-one African American cancer patients were surveyed at two urban cancer centers and asked to agree/disagree to statements related to clinical trials perceptions (facilitators, barriers, beliefs, values, support, and helpfulness), and complete the O'Connor Decisional Conflict Scale. Independent-samples t tests compared participants by clinical trials participation status; 41% had participated in a clinical trial. Results revealed significant perceptual differences among the groups in three main areas: helpfulness of clinical trials, facilitators to participate in clinical trials, and barriers to participating in clinical trials. Post hoc analysis indicated that those who were not asked about clinical trials and had not participated differed significantly in all areas compared with participants. Additionally, clinical trial participants reported significantly lower decisional conflict in most items compared with both those who had and had not be asked to participate. These differences can give practitioners clues as to how to bridge the gap from non-participator to participator. Messages could then be infused in the clinician-patient dyad when introducing and discussing clinical trials, potentially providing a more effective strategy for communicating with African American patients.
